Our Dividend Reinvestment and Direct Stock Purchase Plan "(DRIP") provides interested new investors and holders of record of NorthWestern Energy common stock with a simple and economical method of investing in the Company, through both new cash investments in common stock and reinvestment of cash dividends in additional shares of common stock, without the cost associated with normal brokerage transactions.

There is no discount for shares that are purchased through our DRIP.

Purchases may be made at your discretion by check payment directly to the DRIP administrator.

You may reinvest all or a portion of your cash dividends in additional shares of NorthWestern Energy common stock.

Current shareholders may transfer any currently owned shares to our DRIP for the purpose of dividend reinvestment.

Cash dividends may be deposited directly to your bank account.
